Pro Habber: I could email you a few pics of the house, and property.It's indeed a big house, although its just a 3 bdrm 3 bath, with a few extra rooms, ad good size den, double chininey, 2 "great rooms", one long skinny room the guy used to work out of his home in, a small room with no known designation, and a little workshop room....of course the room where the indoor pool is located.

While I have three distinct cabins currently under construction, I am in the design stage of a indoor pool cabin and returns are off the charts for them. 

Our plan is to install ~600 indoor, climate controlled lockers. 

We replant 300 tress an acre. with 3 and 1's  3 year in doors one year out...

MJ is already in price crash mode.. and indoor grow is expensive.. its not the big money maker people think as prices crash like whats happened here in PDX> not sure in other areas.. but that is the case here.. early in make some good money of course but I think with CA coming in .. and the great out door grow capability here we could see this end up being just another ag play.. not to mention banks won't finance it or bank it

Capital expenditures includes things that will absolutely need to be replaced at some point including your roof, hot water heater, appliances, HVAC(s), floors, carpet, plumbing ,paint (indoors and out), etc.

But her community has 4 club houses, indoor and outdoor pools, shuffle board courts, tennis courts and a lot of other things going on in that community.So that would be the biggest thing you would need to look at, is if the cash flow is there during the seasonal months...  

Account Closed, there are some status-symbol suburbs (think Beverly Hills CA), where it's expected that a pool is standard, and then it just becomes a competition between buyers as to whether a rooftop pool, or indoor heated pool, or cliffhanger pool makes the bigger status statement.

Outdoor water use in single family residential areas can account for a LOT of the total water use compared with indoor use.
